System Structure of NIRVANA

From Darknet to Livenet

Introduction

＊1　nicter real-network visual analyzer

＊2　The collective term for the software that is designed to obtain information without authorization, destroy data, infect other computers, or engage in other abusive behavior. The term covers viruses, worms, Trojan horses, spyware, and bots, and was coined from “malicious” and “software.”

＊3　sFlow is an Internet standard (RFC 3176) for a technology that collects information from network switches, etc., thereby making administration of faster and bigger networks more efficient.

＊4　This data is used for compressing packets into the header information of the network and transport layers and the hash values of the application layer. Compared with livenet traffic, the data volume can be significantly smaller.

Conclusion

＊5　A file format for saving packet information that is flowing on networks. The format is used in many network administration tools (tcpdump, Wireshark, etc.).

＊6　One of the world’s largest annual events in the networking field. Several hundred companies exhibit the latest network devices and solutions and many lectures and conferences are held.

＊7　The network that connects the entire Interop exhibition site. It was created by domestic and international network vendors using state-of-the-art network devices.

＊8　In Figure 2, blue = TCP SYN, yellow = TCP SYN-ACK, green = TCP ACK, pink = TCP FIN, purple = TCP RST, orange = TCP PUSH, light blue = TCP OTHER, red = UDP, and white = ICMP.

＊9　Short for Open Shortest Path First. It is a routing protocol for creating a routing table for the shortest path using Dijkstra's algorithm.

To ver i fy our method for predicting the reception field i nt ens i t y o f LF over l ong distances, we planned to dem-onstrate the method by putting an observation system on a ship. With data acquired from container vessels crossing the Pac i fic and “Sh i ra se”, the Antarctic Observation Vessel, we finally succeeded in devel-oping a calculation method. We would like to thank everyone who has supported us. We will also tell the late Mr. Wakai, who put great efforts into the develop-ment of the prediction method, about our achievement.

◎Comments by the Winner：A countless number of languages are used around in the world. Overcoming the barrier of languages has been a long-held dream of man-kind. In cooperation with other institutes around the world, we proposed a framework for speech translation by connecting through networks the speech recognition, voice synthesis, and transla-tion modules that are widely dispersed in the world. At ITU-T, we worked on the international standardization of communications protocols between modules and the data format. I would l ike to express my deep gratitude to the researchers who have shared the same dream and have been working for over twenty years on speech translation projects, as well as all the supporters who have supported the researchers.

◎Comments by the Winner：

To determine the mechanism of visual perception and conscious-ness , I have been researching a phenomenon called binocular rivalry using the magnetoencephalography device (MEG) owned by the Brain ICT Laboratory. I am greatly honored to have my research receive high recognition by the Biomagnetism and Bioelec-tromagnetics Society. I had difficulty in achieving results and it took me a long time to present the research, but the recognition gives me huge encouragement and I will continue to make every effort to advance the research. I would like to express my sincerest appreciation to everyone in the laboratory who has supported me and given me feedback on the research.
